The diagnosis of concussion has increased dramatically over the past decade, necessitating the acute care provider to have up-to-date knowledge of the definition, pathophysiology, signs and symptoms, physical examination findings, and acute management of pediatric concussion. This article also addresses populations most vulnerable to prolonged recovery from pediatric concussion and referral recommendations. Copyright © 2017 Wolters Kluwer Health, Inc. All rights reserved.
